AI Technical Summary
In the existing electromagnetic gas emergency shut-off valve actuator, the U-shaped inductive bracket and the fixed baffle are only attached by installation, which is not a firm connection, resulting in high assembly difficulty and increased cost.
The design employs a fixed baffle and a U-shaped inductor bracket that engages together. It utilizes the magnetic force generated by the ferrite magnet and the coil on the winding bracket to achieve a stable connection. The stability is further enhanced by the combination of buckles and positioning grooves. The entire part is injection molded into a rubber-coated component for secure connection.
This design achieves a secure connection between the U-shaped inductor bracket and the fixed baffle, reducing assembly difficulty and cost, improving assembly efficiency, and ensuring reliable gas shut-off by controlling the valve's on/off state with magnetic force.
